About Me

Bellabiod Rahyan
Astrochemistry and astrophysics, with a focus on material evolution in extreme environments & Observational Astrochemistry. Interested in using my interdisciplinary background to investigate the formation of key compounds in astronomical settings and the underlying mechanisms of their nanoscale assembly. My focus is on understanding the chemical processes occurring in extreme environments, such as star-forming regions in the outer reaches of galaxies.
